We also faced this not only with print but with logging itself where we wanted to log something visible in the triggerer process but not to the user for debugging. The reason seems to be that supervisor patches stdout and anything logging to stdout is also routed to structlog where it seems to cause issues since the log format "%d" in the _fmt doesn't receive any number or the log of expected format.
